Monday, Uber is launching its JUMP bikeshare service in Seattle, rolling out 300 electric-assist bicycles to start. The company will continue to ramp up the number of red JUMP bikes on Seattle streets in the coming weeks.

Uber is betting it can compete with Lime, the only remaining dockless bikeshare service in Seattle. Three bikeshare companies launched in the area in 2017 as part of a pilot program but only Lime chose to remain in the market when Seattle finalized its permanent permit fees.

Unlike Lime bikes, riders must lock JUMP bikes to a bike rack or post to complete their trips. Uber says the lock-to technology will help reduce sidewalk clutter and improperly parked bikes. JUMP bikes can be unlocked using an ORCA card or user account number.

It costs $1 to unlock a JUMP bike and 10 cents per minute of ride time. That's slightly cheaper than Lime's electric bikes, which cost $1 to unlock and 15 cents per minute in Seattle. Lime also has manual bikes that cost a flat rate of $1 for every 30 minutes of ride time. Uber is offering riders five free 30-minute trips until Dec. 12 as a promotion tied to the Seattle launch.
